Buy Observing the Moon: out of 5 stars NECESSARY BOOK FOR MOON OBSERVATIONS. Reviewed in the United States on Ap Verified Purchase. A very useful book for moon observations. Read more. Helpful. Comment Report abuse. Doc Kinne. out of 5 stars Solid, But Far Too by: 3. An astronomical occultation (pronounced “occ-kull-tay-shun”) occurs when the Moon, an asteroid or another planetary body moves in front of a star, momentarily blocking its light. Occultations are fun to observe, but more importantly they provide important scientific data on the occulting body, the occulted star or sometimes both! Title: Discussion of observations of occultations of stars by the moon, Authors: Newcomb, Simon; Spencer Jones, Harold: Publication: London, H. M. The visual observation of star occultations by the Moon involves the determination of the time of immersion and emersion and requires very few auxiliary devices. Not only is the impressive experience of the motion of our Moon a rich reward in itself, but every observer has here the opportunity of participating in a program that is of great importance for positional by: 1.

OCCULTATIONS OF PLANETS AND BRIGHT STARS BY THE MOON The moon, as our nearest neighbor, sometimes blocks the light coming from a planet, a star, or the sun. Occultations are listed below for May, through The name of the planet or star, along with its visual magnitude, is listed along with the percentage of the moon’s disk. Some angular diameters of stars have been measured by timing of lunar occultations, which is useful for determining effective temperatures of those stars. Early radio astronomers found occultations of radio sources by the Moon valuable for determining their exact positions, because the long wavelength of radio waves limited the resolution available through direct observation. Unit 2:Sun-Earth Connection (Solar System) Lesson Moon Observations. 5E Lesson Planning: I plan most of my science lessons using the BSCS 5E Lesson Model: Engage, Explore, Explain, Elaborate, and a quick overview of the model, take a look at this video.. I use this lesson model because it peaks the students' interest in the beginning during the "Engage" portion and allows for Author: Jennifer Mutch. Occultation of Mars by the Moon. Sunday, , July 6 - The Moon will pass in front of Mars. The pair will visible in the west in the evening sky. At the moment of closest approach, the Moon will be at mag , and Mars at mag , both in the constellation Virgo. Negative observations Paul Leyland 7 .

Observing the Moon's occultations of stars has also resulted in the discovery of binary star systems (double stars) which previously had been missed by telescopes. In these observations, stars appear to fade gradually, or actually in two stages, rather than instantly, thus indicating that there are actually two stars, which may not be clearly. The basic goal of occultation observations is simple: measure the time of the occultation events. We use the term “event” to refer to the time when a star is covered or uncovered by the moon or asteroid. In a total lunar occultation, we measure the time of a single disappearance or reappearance event. Compute predictions for Total Occultations of stars and planets. (Includes: Plot a map of a moon to show where the star will disappear or reappear) Compute predictions for Grazing Occultations of stars and planets. (Includes: Compute the expected lunar limb profile) Record and Reduce Occultation Observations.
